Description: These data represent the output of an analysis by the New York Natural Heritage Program of forest patch condition and value throughout the Hudson River Estuary Watershed and surrounding counties based on remotely sensed data.This layer presents a forest condition index for the Hudson River Estuary watershed and surrounding counties. Forest patches were identified using the 2016 National Land Cover Database and condition was estimated based on a series of metrics relating to fragmentation, ecological value, stressors, and ecosystem services. The layer is intended as a tool for municipal land-use decision-makers, government agencies, land trusts, and other regional conservation partners to prioritize forest areas for conservation and management efforts and provide a baseline for future assessment.Downloaded from NYS DEC GIS clearinghouse in April 2020. Data was revised February 2020. https://gis.ny.gov/gisdata/inventories/details.cfm?DSID=1364Process Description:Forest patches of 100 acres or greater within the Hudson River Estuary Watershed were assessed and scored for multiple aspects of condition, connectivity, stress, and ecosystem value. For each component, patches were ranked based on their condition from highest to lowest, and then assigned a number of points based on their rank, with the largest number of points being awarded to the healthiest patches. The Forest Index was calculated by adding the total points received for all components. For full details on datasets and methods used to calculate the index, see the projected report at https://www.nynhp.org/forest-patches.
